Any plans for coalitions, ie. groups of supergroups? Helpful if you max out a supergroup, or want to have several themed supergroups for your alts, etc.  

We are open to the idea, but we have not coded it yet.

So we will be able to form supergroups with other players. We even can use the same supergroup-house/hideout whatever you call it.
Is there a final decision about the supergroup size? How many players will be able to join?
And can we rename the ranks within the supergoups and create our own ranks?  

There will be supergroups and they will be able to share a base. This feature has not been activated for the Beta. No decision has been made on the maximum supergroup size and we will poll our community before making a decision.

You will be able to rename/create your own supergroup ranks.
